Did early church Fathers or protestant reformers believed in coming of Jesus will be secret?
No, this doctrine was not taught by early church Fathers and protestant reformers
Is there any biblical base for secret rapture doctrine?
Bible talks about Jesus coming unexpectedly (suddenly) without any information but there is no single Bible verse which tells that Jesus coming will be secret.
If it is not taught by early church Fathers and protestant reformers and neither it is found in the Bible then how did this come into christianity?
Protestant reformation movement believed and taught that Pope is the antiChrist. The catholic church wanted to divert this charge of Pope as antichrist by turning away the focus of antichrist into future.
Jesuit doctor of theology, Francisco Ribera, in his book Sacrum Beati Ioannis Apostoli, & Evangelistiae Apocalypsin Commentarij proposed that the prophetical periods of 1260 days, 42 months and three and half years into future and do not apply to Papacy.

Manuel De Lacunza (1731-1801), a Jesuit priest from Chile, also advocated futurism in his manuscript entitled La Venida del Mesias en Gloria y Magestad (“The Coming of the Messiah in Glory and Majesty”). Writing under the assumed name of Juan Josafa (Rabbi) Ben-Ezra, Lacunza hoped to obscure the fact that he was a Catholic, in order to give his book better acceptance in Protestantism. Church of Scotland minister, named Edward Irving, was influenced by this book and translated it.
John Darby, an Englishman and pioneer of the “Plymouth Brethren” movement became caught up in the rapture philosophies of Irving. When Darby heard about Irving’s activities, he traveled to Scotland to talk with Irving and his followers about the “secret rapture”. It was Darby who became the master developer of “scriptural” arguments to support the theory/doctrine that evolved.
Darby’s development of the “rapture” theory has since become widely popularized in Britain and finally in the U.S., largely as a result of Cyrus Scofield’s notes in his Scofield Reference Bible.
What manner of coming will be Jesus second coming?
Bible tells us that second coming of Jesus when the saints gets resurrected will be loud, noisy and the whole world including the wicked will see it. It will be an unexpected event but not a secret event. The dead in Christ will rise up on this day.
2Pe 3:10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
Note. 1. The day will be unexpected for the Lord comes like a thief 2. heavens shall pass away with great noise
1Th 4:16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
Note. 1. Lord will descend with a shout and with the trump. 2. The dead in Christ shall rise first.
1Co 15:52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
Note: 1. The trumpet will sound. Trumpet ofcourse is a very loud instrument 2. The dead in Christ will rise up.
